Glyphidocera speculae , new species

(Figs. 228–230, 363, Map 42 )

Diagnosis.— Glyphidocera speculae is most similar to G. vestita but differs from the latter by having an abdomen with more rows of sex scales between terga 2–3 in male, a tegumen that is narrower basally, wider costal furcae of valva, a more angular apicoventral margin of cucullus, and an apical cornutus without a bulbous base, and the absence of within vesica.

Description.— Head: Vertex and frontoclypeus pale orange intermixed with few paleyellow scales; outer margin of labial palpus with segments I–II brown intermixed with pale­orange scales to apical margin, segment III brown with few pale­orange scales on apical half; inner surface pale orange intermixed with few brown scales; scape of antenna pale orange intermixed with few brown scales, flagellum with alternating bands of brown and pale­orange scales; male 4th flagellomere dorsally protuberant and curved, forming a deep concavity opposite slightly excavated flagellomeres 5–6; concavity nearly closed by a few setiform scales on apex of protuberance of 4th flagellomere; proboscis pale orange.

Thorax: Tegula brown basally, pale orange distally; mesonotum pale orange. Legs pale yellow intermixed with pale­orange and few brown scales, pale yellow to apical margin of all segments and tarsomeres. Forewing (Fig. 363): Length 6.9 mm (n = 1), pale orange intermixed with pale­yellow scales, and brown scales along costa and from near distal end of cell to margin. Undersurface brown. Hindwing: Pale brown.

Abdomen (Fig. 228): Male with 5 transverse, irregular rows of sex scales on intersegmental area between terga 2–3.

Male Genitalia (Figs. 229–230): Uncus elongate, wide at base, broadly constricted at 1/3, slightly rounded distally, apex narrowly rounded and setose; gnathos sparsely setose, protuberant, wide basally, gradually narrowing apically, upturned apically; tegumen narrow, slightly widened basally; dorsal strut of tegumen with arms convergent basally and dorsally, forming an elliptical­shaped sinus between points of constriction, dorsally atrophied; valva with costa slightly sloped from a shallow depression beyond a slanted, basal, digitate process to dorsal furca; apex widely bifurcate, furcae slightly divergent, dorsal furca large, falcate, ventral furca extending slightly beyond outer margin of cucullus; sacculus twisted apically, constricting valva near midlength, widening distoventrally, forming an elongate and slightly angular cucullus; cucullus membranous, setose; vesica denticulate, bearing a moderately large, hornlike, apical cornutus; cornutus with one side slightly shortened, exposing a hollow, basal cavity.

Female Genitalia: Unknown.

Distribution ( Map 42 ): Glyphidocera speculae is known from a single collecting site on the Osa Peninsula in south­eastern Costa Rica.

Etymology: The species epithet speculae is derived from the Latin “specula,” meaning watchtower.
